Hello. I disconnected the battery in my 2001 X5 when removing steering wheel to rapair the BC button. The BC button now works but when I turn the key to run the horn blasts on/off. the car will start but i have extra lights on the dash. The parking brake light stays on yellow (red if i pull the lever) the abs light stays on, and the stability control light stays on as well. The remote still works to turn the alarm on/off and unlock/lock doors.

I called a dealership and a mechanic said there could be a voltage imbalance between the car battery and alarm battery. He suggested putting a charger on battery but that didnt fix anything.

I have tried connecting battery with key in run position, no fix.

Everything worked fine before I disconnected the battery. Does anyone know what I have to do to fix this?
